摘要
提出了一种基于DSP的恒流源控制方法,在该恒流源系统中,通过改变PWM波形占空比对电流进行数字化控制,控制方式采用模糊PI算法。文中给出了整个系统的软硬件实现方案并进行了实验测试。测试结果表明,这种基于DSP的电流控制方法,具有调节速度快、控制方式灵活、电流稳定性高等优势。
A kind of constant current source control method based on DSP is presented in this paper.In this system of constant current source,the current is controlled digitally through changes of the duty ratio of the PWM waveforms.And the control manner adopts the fuzzy PI algorithm.The paper presents the implementation schemes of both hardware and software of the whole system,and performs testing with experiments.The testing results show that this DSP-based curent control method has the advantages of quick adjustment speed,flexible control manners,current stability and so on.
